“Starting today, you can now call and chat with your Skype contacts while in Office Online and OneDrive. This creates a natural, collaborative experience where you can co-edit a document right alongside a chat so that the chat is in context of the topic being discussed. Best of all, this chat history stays connected to the document the next time you open it to help you pick right up where you left off.”

Now, whenever you use Word, Excel, PowerPoint, or OneNote, you can simultaneously collaborate with someone via Skype instant messaging or video chat. OneDrive offers a similar Skype experience.
